System Time zone settings
During the learning process, it was found that the time obtained through the date () function is different from the local time, because PHP5 has rewritten the date () function, so the current datetime function is 8 hours less than the system time.

JetsonTX2 is being studied to develop an image acquisition module. According to the L4T documentation, the DTSi file with the camera module is rewritten, and the image file and DTS folder are generated by renumbering the kernel on the board. That's all right, then. After updating the kernel and DTB according to the documentation, unexpected problems have occurred. The update kernel method described in the document is to copy the image to the/boot dire
How to identify the number of physical CPUs, a few cores, is hyper-threading or multi-core
Judge the basis:
1. CPUs with the same core ID are the same core hyper-threading.2. CPUs with the same physical ID are the same CPU-encapsulated threads or cores.
English version:
1.Physical ID and core ID are not necessarily consecutive but they unique. Any CPUs with the same core ID are hyperthreads in the same core.2.Any CPU with the same physical ID are threads or cores in the same socket.

The next important function of MT is threadloop_mix. Because there is a timedtrack class, the process function of audiomixer carries a timestamp, PTS, and presentation timestamp. From the codec perspective, t
1. Import or export data using the DTs designer
The DTS designer is powerful and supports multi-task operations. It is also a visual interface and easy to operate. However, there are not many people who know it. If you only want to move the table shards in the SQL Server database, it is best to use this method, of course, you can also move all tables. In SQL Server Enterprise Manager, expand + on the le
